02. Command decoding, memory access and syscalls
Command decoding (I, R, J and their fields), probably using Python commandline
Mnemonic pseudoinstruction (e. g. move $t1 $t2 instead of addui $t1 $zero $t2)
- Memory access (load/store)
- Calculating address (register + immediate offset)
pseudoinustruction (lui $at halfword + …)
- Simple mars program
The syscall concept
- Read integer, write integer and halt syscalls
